Whose Burden is it to Recycle Computers?

bostons asks: "California places the financial burden of dealing with the electronic waste on consumers, charging a $6 to $10 disposal fee on every computer and television purchased. Maine puts the onus on manufacturers, demanding they pay the full cost of recycling their computers or televisions and pick up a share of the recycling tab for products of unknown origin. Starting next year, Maryland will require manufacturers to offer free computer take-back programs or pay the state a fee. Which do you think is the most effective and appropriate option?"
